Procedure

A solution of 300 mg (0.58 mmol) of 2-{ethyl-[4-(2,2,2-trifluoro-1-triethylsilanyloxy-1-trifluoromethyl-ethyl)-phenyl]-amino}-1-phenyl-ethanol in 7.5 mL of THF was treated with 1.5 mL of a 1M TBAF-solution in THF and stirred at RT for 1 hour. Evaporation of the solvent and column chromatography on silica gel with n-heptane/EtOAc 9:1 yielded 153 mg (65%) of 2-{4-[ethyl-(2-hydroxy-2-phenyl-ethyl)-amino]-phenyl}-1,1,1,3,3,3-hexafluoro-propan-2-ol, white solid, MS: 408 (MH+).
